public class BinaryCompareDefinition_I32
extends Object

Describes the layout of a BRIEF descriptor. This descriptor is composed of a set of locations where image intensity is sampled and a list of which locations are compared against each other.

NOTE: The data structure here is different than the one implied in the paper. A single list of sample points is provided instead of two lists. This way a single set of points can sample within the same set, reducing the number of samples taken.
